AUTOMATIC COMPUTING AND WEIGHING SCALE.

SPECIFICATION forming part of Letters Patent No. 726,182, dated April 21, 1903. Application filed October 27, 1902- I Serial No. 128,857. No model.)

To aZZ whom it may concern:

Be it known that LTIMOTHY S.MoUN'r,a citizen of the United States, residing at Rhome, in the county of Wiseand State of Texas, have invented certain I new and useful Improvements in Automatic Computing and Weighing Scales, of which the following is a specification.

This invention relates to weighing-scales, and more particularly to scales which will weigh and compute and indicate the total cost of goods or articles at any ordinary price per pound; and the object is to construct a weighing machine or scale which will indicate absolutely correct weights and which can be readily set to compute the cost of articles at any reasonable price per pound and which will indicate the total weight and the total cost.

Other objects are to construct a weighingmachine which is simple inv construction, which can be manufactured at small cost, and which is practical and durable.

The construction will be fully explained in the following description, and the invention a will bemore' particularly pointed out in the appended claims.

Reference is had to the accompanying drawings, which form a part of this specification and application.

Figure 1 is a front elevation of the scales in detail. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section of one of the sliding weights, showing the manner of holding the weights at any adjustment on the weighing-cross. Fig. 4 illustrates an additional weight which maybe added to the lower sliding weight.

Similar characters of reference are used to indicate the same parts throughout the several views.

The scales are provided with a suitable base 1 and an uprightframe-piece 2. A cross having arms 3, 4, 5, and 6 is pivotally mounted on the frame-piece 2and the upright bearing 7. The frame 2 and the bearing-piece 7 may be attached or bolted to the base 1 in any suitable manner. The bearing-piece 7 must be placed on one side of the cross A, so that it will not obstruct the movements of the sliding weights, hereinafter described. The

pivotal-rock-shaft 8 must have a bearing on each side of the close A. Sliding weights 9 and 10 are mounted on the arms 4 and 6 of the cross A, respectively. The weights 9 and 10 are connected by a bar 11. One of the weights, as weight 9, may be made integral with the bar 11. The other weight, 10, would have to be. secured to the bar 11, and the weight may be secured to the bar by inserting the endof the bar in the weight and securing the bar in the weight by means of a pin 12. Additional weights 13 may be placed on the weight 10. The additional weight 13 would occupy the position shown by dotted outline in Fig. 1. A scale of prices may be made on the arm 4, and the top edge of the weight 9 may be the indicator. The weights 9 and 10 are slidable on the armstand 6 and are held against sliding by means of springpressed clasps 14, which have edges pressed against the arm 4 of the cross by means of the springs 15, mounted in a cut-out in the weight 9. The clasps 14 extend out of openings in the front'side of the weight, so that they can be grasped by the fingers. A person can take hold of the clasps and set the weight so that the top edge of the weight will stand atany'price marked 011 the arm 4. The article tobe weighed is suspended from the arm 3. The rod 16, which is pivotally attached to arm 3 and provided with a hook 22, illustrates one way of suspending articles to be weighed. The hook 22 may engage the lever of any suitable platform. The weight of the article causes the arms of the cross to rock or turn in the direction of the hands of a clock. An arm or beam 17 for making a scale of total cost of articles is attached'to the frame-piece 2 and to an arm 18 of said frame-piece. A scale oftotal costs from five cents up to any convenient sum may be made on the beam 17, as up to five dollars or ten dollars. The beam 17 will have to be located by experiment. The spaces between the total-cost marks must be of equal width. This" beam 17 may .be in or near a horizontal position. The edge of the arm 4 is the indicator for the total cost or the total weight-that is, this arm will be rocked or turned by the weight of the article, so that the edge of the arm 4 will stop at the particular mark on the beam 17 which will indicate the cost of the article or the weight of the ar-' ticle. For instance, an article weighing three pounds is placed on the scales and the cost of the article being seven cents a pound, move up the weight 9 to the7 cts. mark. The arm 4 will move in a curve or rock until the edge of the arm 4will stop at the 21 cts. mark on the beam 17, or, it it is desirable to determine the weight of the article, set the weight 9 at the 1 ct. mark and place the article on the scales. The arm 4 will move until it stops at the mark 3 on the beam 17, which will mean that the article weighs three pounds. Thus the marks on the beam 17 can represent cents or pounds.

Another illustration: A party wants seventy-five cents worth of something that is worth siX cents a pound. Move the weight 9 to the 6 cts. mark on the arm 4. Then place enough of the article on the scale to cause the arm 4 to turn or rock until the edge of the arm 4 stops at the 75 cts. mark on the beam 17. If the beam 17 has notation for only ten dollars and a party wants more than ten dollars worth, place a Weight 13,

which represents ten dollars or one thousand pounds, on the weight 10 and proceed as above. It the party wan ted as much as fourteen dollars and fifty cents worth of fourcent goods, set the weight 9 at the 4 cts. mark. Then put the goods on the scales until the arm 4 stops at the $4.50 mark on beam 17. The party would have three hundred and sixty-two and one-half pounds of fourcent goods. The weights 13 may be made to indicate any convenient amount or represent any convenient weight,as one-hundred pound weight, two hundred pound weight, 850., and the same weight 13 may represent one dollar, two dollars, &c.

Weights may be placed on the weight 10 or on the arm 5 or arm 4. To illustrate: It a party wants more of an article than the scale above described will compute, as one hundred and thirty-seven pounds of seventythree-cent goods, put a weight 13, representing one hundred dollars, on weight 10, set the weight 9 at the 1 ct. mark, put goods on the scales until the arm4 registers 137 on the beam 17. This determines the pounds. Then set the weight 9 at the 73 cts. mark on arm 4. The arm 4 would then register 1 ct. on the beam 17. This one cent, with the one hundred dollars represented by the weight 13, would make one hundred dollars and one cent, the cost of the goods. The same result may be reached in another way. Move the weight 19 so that it will register one hundred pounds on the arm 5. Set the Weight 9 at the 1 ct. mark on the arm 4, put on goods until the arm 4 registers 37 on the beam 17. This thirty-seven pounds, with the one hundred pounds represented by the weight 19, would be the weight. Then set the weight 9 at the 73 cts. mark on the arm 4. The arm 4 would then register$27. 01 on the beam 17. This twenty-seven dollars and one cent, with the seventy-three dollars,

the cost of one hundred pounds, would make the one hundred dollars and one cent. If the arm 4 does not show prices above one dollar and a party wanted goods worth one dollar and twelve cents, weights 20 may be placed on top of the arm 4. Put a one-dollarweight on top of the arm 4 and move the weight 9 to the 12 cts. mark on the arm 4. The arm 4 will then register the correct total cost on the beam 17. The weight must be determined before the weight 20 is placed on the arm 4.

For simply weighing an article set the weight 9 at the 1 ct. mark on arm 4 and put the article on the scales. The arm 4 will register the weight of the article on the beam 17. If the weight of the article is too great to be weighed in this manner, move the weight 19 on the arm 5 to represent one hundred, two hundred, &c., pounds, which must be added to the pounds registered by the arm 4 on beam 17 Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
